Martin Holst Swende	efe6dd2904	consensus/ethash: implement faster difficulty calculators (#21976) ... This PR adds re-written difficulty calculators, which are based on uint256. It also adds a fuzzer + oss-fuzz integration for the new fuzzer. It does differential fuzzing between the new and old calculators. Note: this PR does not actually enable the new calculators.	4 years ago

Felix Lange	225de7ca0a	tests: update tests and implement general state tests (#14734) ... Tests are now included as a submodule. This should make updating easier and removes ~60MB of JSON data from the working copy. State tests are replaced by General State Tests, which run the same test with multiple fork configurations. With the new test runner, consensus tests are run as subtests by walking json files. Many hex issues have been fixed upstream since the last update and most custom parsing code is replaced by existing JSON hex types. Tests can now be marked as 'expected failures', ensuring that fixes for those tests will trigger an update to test configuration. The new test runner also supports parallel execution and the -short flag.	7 years ago

Jeffrey Wilcke	10a57fc3d4	consensus, core/*, params: metropolis preparation refactor ... This commit is a preparation for the upcoming metropolis hardfork. It prepares the state, core and vm packages such that integration with metropolis becomes less of a hassle. * Difficulty calculation requires header instead of individual parameters * statedb.StartRecord renamed to statedb.Prepare and added Finalise method required by metropolis, which removes unwanted accounts from the state (i.e. selfdestruct) * State keeps record of destructed objects (in addition to dirty objects) * core/vm pre-compiles may now return errors * core/vm pre-compiles gas check now take the full byte slice as argument instead of just the size * core/vm now keeps several hard-fork instruction tables instead of a single instruction table and removes the need for hard-fork checks in the instructions * core/vm contains a empty restruction function which is added in preparation of metropolis write-only mode operations * Adds the bn256 curve * Adds and sets the metropolis chain config block parameters (2^64-1)	8 years ago
Péter Szilágyi	09777952ee	core, consensus: pluggable consensus engines (#3817) ... This commit adds pluggable consensus engines to go-ethereum. In short, it introduces a generic consensus interface, and refactors the entire codebase to use this interface.	8 years ago
